umdl: mark paths containing /stage/ also as testing

[adrianreber]

As described in

https://fedorahosted.org/fedora-infrastructure/ticket/5185

umdl picks up repositories and versions in the alt/ tree in the staging directory, which should not be presented on the MirrorManager main page.

umdl already has a check to see if a version is a test version and this is now extended to also mark releases/repositories/versions in paths containing 'stage' as 'isTest'.
